Detailed Description

A p-code operation in a SLEIGH specification.

Each input and output to the operation is a VarnodeTpl.

Constructor & Destructor Documentation

~OpTpl()

ghidra::OpTpl::~OpTpl

(

void

)

Destructor.

An OpTpl owns its VarnodeTpl.

References input, and output.

Member Function Documentation

changeHandleIndex()

void ghidra::OpTpl::changeHandleIndex

(

const vector< int4 > &

handmap

)

Remap any handle indices for inputs and outputs to this.

This is used to help reorder sub-constructors. Each input and output VarnodeTpl is remapped using the given array of handle indices

Parameters

handmap

is the given array of new handle indices

decode()

void ghidra::OpTpl::decode

(

Decoder &

decoder

)

Decode this OpTpl from a stream.

Parameters

decoder

is the input stream

encode()

void ghidra::OpTpl::encode

(

Encoder &

encoder

)

const

Encode this OpTpl to an output stream.

Parameters

encoder

is the output stream

References ghidra::Encoder::closeElement(), ghidra::VarnodeTpl::encode(), encode(), input, opc, ghidra::Encoder::openElement(), output, and ghidra::Encoder::writeOpcode().

removeInput()

void ghidra::OpTpl::removeInput

(

int4

index

)

Remove the indicated input.

Parameters

index

is the index of the input to remove
